Media Rights Management on Multiple Devices

1. A system, comprising: a fragment server configured to receive a request from a user to access a piece of media content at a first service level, the fragment server including a processor, the fragment server configured to fragment MPEG-4 files without out of band signaling, wherein a box structure is provided to include synchronization information and chapter information, wherein the synchronization information is used to synchronize audio and video when playback entails starting in the middle of a stream and chapter information signals when the current program or file is over; a storage device configured to maintain a service level authorized for the user; wherein the fragment server is configured to access the storage device to determine whether the user is authorized to receive media content at a first service level at a first device and whether the user is authorized to receive media content at a second service level at a second device, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device.

2. The system of claim 1 , wherein the media content transmitted to the first device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a first quality level.

3. The system of claim 2 , wherein the media content transmitted to the second device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a second quality level.

4. The system of claim 1 , wherein the box structure further includes end of file information.

5. The system of claim 1 , wherein the media content transmitted to the second device corresponds to media content transmitted to the first device.

6. The system of claim 1 , wherein the position where playback is stopped at the first device is identified.

7. The system of claim 1 , wherein the media content transmitted to the second device begins where playback is stopped at the first device.

8. The system of claim 7 , wherein the second device is a set top box.

9. The system of claim 7 , wherein the second device is associated with a television screen.

10. The system of claim 1 , wherein if the user is not authorized to receive the media content at the second service level, a message is transmitted to the user.

11. A method, comprising: identifying a user; authorizing the user to access a piece of media content at a particular service level by using a fragment server configured to fragment MPEG-4 files; receiving a first request from a first device to receive the media content, the request associated with a first service level, wherein the first request is received at the fragment server, the fragment server configured to fragment MPEG-4 files without out of band signaling, wherein a box structure is provided to include synchronization information and chapter information, wherein synchronization information is used to synchronize audio and video when playback entails starting in the middle of a stream and chapter information signals when the current program or file is over; determining that the user is authorized to receive the media content at the first service level by accessing stored service level authorized for the first device; transmitting the media content to the first device; receiving a second request from a second device to receive the media content, the request associated with a second service level; determining whether the user is authorized to receive the media content at the second service level by accessing stored service level authorized for the second device, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device.

12. The method of claim 11 , wherein the media content transmitted to the first device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a first quality level.

13. The method of claim 12 , wherein the media content transmitted to the second device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a second quality level.

14. The method of claim 11 , wherein the box structure further includes end of file information.

15. The method of claim 11 , wherein the media content transmitted to the second device corresponds to media content transmitted to the first device.

16. The method of claim 11 , wherein the media content transmitted to the second device begins where playback is stopped at the first device.

17. The method of claim 11 , wherein the position where playback is stopped at the first device is identified.

18. An apparatus, comprising: means for identifying a user; means for authorizing the user to access a piece of media content at a particular service level; means for receiving a first request from a first device to receive the media content, the request associated with a first service level, wherein the first request is received at a fragment server, the fragment server configured to fragment MPEG-4 files without out of band signaling, wherein a box structure is provided to include synchronization information and chapter information, wherein the synchronization information is used to synchronize audio and video when playback entails starting in the middle of a stream and chapter information signals when the current program or file is over; means for determining that the user is authorized to receive the media content at the first service level by accessing stored service level authorized for the first device; means for transmitting the media content to the first device; means for receiving a second request from a second device to receive the media content, the request associated with a second service level; means for determining whether the user is authorized to receive the media content at the second service level by accessing stored service level authorized for the second device, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device.
